Reference Guide Fire Strategy

1.5.17 Party Walls

Where walls are shared with adjacent tenancies these are required to achieve the relevant

fire resistance as recommended in Approved Document B (minimum 60/60/60). This
requirement increases dependent on the height of the building in which the demise is

situated.

1.5.18 Compartment Floors

Floors that separate ground and first floor levels under Co-op ownership should achieve not
less than 30/30/30 fire resistance where detection is provided throughout the first floor.

Where this level of coverage is not achieved, this requirement should be increased to
achieve not less than 60/60/60 REI.

Independent tenancies, such as residential or retail premises, situated above/below the store

shall be separated by the provision of compartment floors. Compartment floors shall achieve
not less than 60/60/60 fire rating. It should be noted that a higher fire rating may be required
in large complexes, and the recommendations of Approved Document B should be adhered

to in all cases.

1.5.19 Fire Doors

Fire doors should satisfy the following requirements, as specified in Approved Document B:

Position of Door Required Door Installation
Protected Stair Enclosure FD30s
Forming part of an enclosure to a FD30
place of special fire hazard
In a compartment wall separating FD 60
Purpose groups / Compartments

1.5.20 Areas of Special Fire Risk

Areas of special fire hazard are required to be provided with fire resisting construction
achieving not less than 30/30/30 construction. ADB defines an area of special fire hazard as
follows:

“Oil-filled transformer and switch gear rooms, boiler rooms, storage spaces for fuel or other
highly flammable substances and rooms housing a fixed internal combustion engine”.

It is noted that no areas of the model store design are considered areas of special fire
hazard under ADB and thereby no additional fire resistance is required. It is further noted
that as a property protection measure it may be preferable to provide fire resistance to such

areas that pose an increased risk of fire, such as the bakery prep area.
